Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembly stand for preliminarily assembling a lining plate outside a tunnel in order to install a PC lining plate on a lining portion in repair lining of an existing tunnel or the like. .

[0002]

2. Description of the Related Art Conventionally, as a method of lining with a PC lining plate, generally, the lining plate is transported from the outside of the tunnel to the inside lining portion by a truck or the like and travels along a rail laid inside. The method of assembling by sequentially installing one by one in the lining section by the installation machine is adopted.

[0003]

In the repair lining of an existing tunnel, even if the installation machine is formed in a gate shape and a general vehicle can pass under it, the lining plate is transported by a truck or the like. When loading and unloading vehicles, the passage of ordinary vehicles is obstructed, and the rails obstruct the passage in a narrow tunnel.

Since the assembly and lining work must be performed inside the tunnel and in a narrow space between the installation machine and the installation machine, the work is difficult and the construction efficiency is poor, and it is not easy to secure the work safety and maintain the installation accuracy.

[0005]

According to the present invention, a fixed supporting base fixed on a base and a fixed supporting base are installed so as to be movable back and forth in a direction opposed to the fixed supporting base by a feed moving mechanism. The movable support base, a plurality of lateral feed rollers attached to the front ends of the fixed support base and the movable support base facing each other, and the horizontal feed rollers attached to the rear parts of the fixed support base and the movable support base at a position lower than the front upper end thereof. From the feed rail and the underframe that is detachably attached to the middle of the inner surface of the lining plate that is supported on the fixed support and the movable support, and that supports the support roller that is placed on the horizontal feed rail and movably supported. We propose an assembly stand for the tunnel lining plate.

[0006]

[Operation] In the assembly frame installed outside the tunnel where there is no restriction as a working space, a plurality of arc-shaped PC lining plates are joined and integrated in the front, rear, left and right, so that an arch type assembly lining plate for a plurality of spans can be safely and efficiently installed. Assemble.

At the time of this assembly, the upper portions of the arc-shaped PC lining plates are movably mounted on a plurality of transverse feed rollers attached to the upper ends of the front portions of the fixed support base and the movable support base, respectively. The traverse rail mounted at a position lower than the upper end of the front part supports the supporting roller of the underframe detachably mounted in the middle of the inner surface of the lining plate so that it can move freely and is positioned and held. Is moved to the fixed support base side and the lining plates on both support pedestals are joined at their upper ends, and the lining plates are joined and integrated by bolts or joint hardware.

The lining plates thus assembled are stacked and supported on the support frame of the transportation and installation machine, transported to the lining section inside the tunnel by the transportation and installation machine and installed, and then the transportation and installation machine is installed outside the tunnel. Drive backwards.

While the transport installation machine reciprocates, the process of assembling a new lining plate on the assembly stand in the same manner as above and again transporting it to the lining section by the transport installation machine and sequentially installing it is repeated.

In the lining section, the vehicle body of the transportation installation machine is stopped in the vicinity of the preceding lining board, and the lining board on the support frame is attached to the lining board previously installed by the rear pressing member. Advance and join until they abut.

In this case, if the support height or inclination of the lining plate on the support base does not match the installation level of the preceding lining plate, level adjustment is performed while vertically adjusting the four-point elevation adjustment mechanism.

Further, when the front end surface of the lining plate on the support pedestal is not parallel to the rear end surface of the preceding lining plate, the traverse beam is moved in opposite directions to adjust the direction together with the support pedestal. If the front surface of the lining plate on the support base is misaligned in the left-right direction with respect to the rear end surface of the preceding lining plate, move the transverse beam in the same direction and position it with the support base. Make adjustments.
